ORNL team develops 3D interconnected polymer/ceramic composite as a thin film solid electrolyte

Green Car Congress

Oak Ridge National Laboratory researchers have developed a thin-film, highly conductive solid-state electrolyte made of a polymer and ceramic-based composite for lithium metal batteries. There are two classes of solid electrolytes, inorganic oxide- or sulfide-based electrolytes and polymer-based electrolytes. —Palmer et al.
